£30.00

This listing features a stunning polished Cadoceras sublaeve Ammonite Fossil, originating from the Kellaways Clay Formation, dated to the Lower Callovian Stage of the Middle Jurassic, approximately 165 million years ago. This fossil was found in Ashton Keynes, Wiltshire, United Kingdom, and is part of the esteemed Alice Purnell Collection.

Cadoceras sublaeve is a beautifully ribbed ammonite species characterised by its wide whorls and distinct ornamentation. Ammonites were marine molluscs that thrived in the oceans for millions of years before their extinction at the end of the Cretaceous period. Their coiled shells and evolutionary diversity make them an iconic fossil type, prized by palaeontologists and collectors alike.

The Kellaways Clay Formation, part of the larger Great Oolite Group, represents marine depositional environments rich in clays and fine silts that aided in the remarkable preservation of marine fossils like this one. Ammonites from this locality are particularly known for their completeness and scientific value.

This specimen has been expertly cut and polished, revealing the intricate internal chamber structure of the ammonite. The polish enhances the natural mineralisation within the fossil, providing a captivating glimpse into the ancient marine world.
